A 500 ml bottle of Central Heating Sludge Remover paired with a handy Radiator Dosing Funnel gives you a fast, mess‑free way to clean boilers, radiators and heat exchangers. Over time, silt, sand and flux build up inside the system, restricting water flow and reducing heat efficiency. This concentrate dissolves those deposits without harming metal components, helping your heating system run smoother and last longer.
What’s inside the kit
– 1 × 500 ml sludge‑remover concentrate (dose‑marked bottle)
– 1 × 1‑litre nylon dosing funnel with brass ½” BSP male thread and swivel joint
How it works
1. Attach the funnel to the radiator’s ½” BSP tap – it fits 99 % of domestic radiators.
2. Pour the recommended amount of concentrate into the funnel; gravity does the rest.
3. In about 17 seconds the chemical reaches the system, flushing out sludge and restoring optimal water flow.
